These Terms explain the rules for using DepreciationsCalculator.co.uk and our free UK depreciation, vehicle value, business asset and capital allowance calculators. They are written in plain English so users understand what the tools can and cannot do.
This summary helps you understand the main points. The full Terms below still apply and should be read carefully.
You may use the calculators for planning and education, but we do not guarantee that every output is accurate for your individual tax, accounting or valuation position.
Outputs are not tax, legal, accounting, investment, valuation or financial advice. Use a qualified professional before filing returns or making important decisions.
You must not scrape, copy, overload, reverse-engineer or misrepresent our tools. Accountants may use them for illustrations only with independent review.
Nothing in these Terms is intended to exclude liability where UK law does not allow exclusion, including liability for death or personal injury caused by negligence.
By accessing DepreciationsCalculator.co.uk, browsing our guides, using any calculator, downloading any template, or relying on any result generated by the website, you agree to these Terms of Service. If you do not agree, you should stop using the website and its tools immediately.
These Terms apply to all pages and tools on the Site, including depreciation calculators, capital allowance calculators, car value tools, property calculators, fixed asset templates, depreciation tables, glossary pages and related educational articles. They also apply to future versions of those tools unless we publish separate terms for a specific product.
We may refer to the website and tools together as the “Services”. References to “we”, “us” and “our” mean DepreciationsCalculator.co.uk. References to “you” mean the person or organisation using the Services, whether as an individual, sole trader, company director, employee, accountant, adviser or visitor.
DepreciationsCalculator.co.uk is an informational website focused on UK depreciation, asset values and capital allowance calculations. The Site provides calculator-style content for educational use by UK drivers, landlords, sole traders, small businesses, company owners, finance teams and professional advisers.
We are not HMRC, Companies House, a regulator, a law firm, an accountancy practice, a tax adviser, a financial adviser, a car valuation house, a surveyor or a regulated investment business. Any references to HMRC, GOV.UK, UK GAAP, FRS 102, RICS, CAP HPI, Glass’s Guide, auction values or market data are explanatory only unless expressly stated otherwise.
The Services are designed to help users understand depreciation and capital allowance concepts. Our tools may estimate straight-line depreciation, reducing balance depreciation, net book value, residual value, car value loss, electric vehicle depreciation, van depreciation, business asset depreciation, Annual Investment Allowance, Writing Down Allowance, First Year Allowance, Structures and Buildings Allowance and related figures.
Calculator results are based on the information you enter, default assumptions coded into the tool, published rates, simplified examples and general market logic. A result may include a year-by-year schedule, monthly depreciation estimate, projected future value, tax-saving illustration, pool balance, allowance claim or summary table.
The Services are not designed to be a complete tax computation system. They do not track your full purchase history, disposals, private-use adjustments, transitional periods, group relief restrictions, accounting period apportionments, VAT treatment, balancing adjustments, connected party transactions, lease classification, R&D treatment, grants, subsidies or all other matters that may affect a real calculation.
All calculators, tables and guides are provided for general educational and planning purposes only. The figures are intended to help you understand how a calculation might work, not to replace a full professional review. For example, a business car allowance output may show how a low-emission vehicle could enter a capital allowance pool, but it will not confirm whether your actual vehicle, contract, emissions certificate and tax profile qualify for that treatment.
The same principle applies to property, land and commercial building tools. A calculator can show a simple land/building split or a possible SBA schedule, but it cannot provide a RICS valuation, verify construction expenditure, check all qualifying conditions or determine whether your purchase agreement has been structured correctly.
You should treat every output as a working estimate. Before using a figure for accounts, tax returns, finance applications, insurance schedules, sale negotiations, commercial decisions or legal disputes, you should check the source data and obtain professional advice where appropriate.
UK tax rules, accounting standards, company car rules, vehicle benefit rates, capital allowance rates, thresholds and reliefs may change. Even when a page title refers to 2026, a rule may have a different commencement date for Corporation Tax, Income Tax, accounting periods or transitional periods. Your own year-end date may also produce blended or apportioned rates.
Market data can change even faster. Car depreciation, classic car values, commercial property yields, used EV values and fleet residual values depend on demand, supply, mileage, condition, brand, specification, colour, service history, battery health, region and wider economic conditions. Calculator defaults are broad assumptions and cannot predict your actual sale price.
You agree that it is your responsibility to verify the latest position using official guidance, legislation, professional software, valuation databases or qualified advisers before relying on a result.
The Services do not constitute tax advice, legal advice, accounting advice, audit advice, investment advice, vehicle valuation advice, property valuation advice or regulated financial advice. The Site does not create an adviser-client, accountant-client, solicitor-client or fiduciary relationship between you and us.
You remain responsible for the accuracy of your accounts, Corporation Tax return, Income Tax return, VAT return, payroll filings, company records, asset register, capital allowance computation and any other documents submitted to HMRC, Companies House, lenders, insurers, investors or counterparties.
Where a calculator refers to HMRC rules, that reference is only a simplified explanation. HMRC may take a different view based on facts we do not know. For tax filing, you should use official guidance, current legislation and professional advice that reflects your complete circumstances.
When using the Services, you are responsible for entering accurate inputs, understanding the assumptions shown by the tool and checking whether those assumptions match your situation. If you enter the wrong purchase price, useful life, CO₂ figure, business-use percentage, land allocation, pool balance or tax rate, the output will also be wrong.
You are also responsible for keeping independent records. Calculator results are not a substitute for invoices, contracts, mileage logs, V5C documents, valuation reports, fixed asset registers, disposal evidence, lease agreements, accounting policies or tax computations.
| Your task | Why it matters |
|---|---|
| Check source data | Calculator accuracy depends on your purchase cost, date, useful life, residual value, mileage, emissions and pool balances. |
| Review current law | Tax rates and reliefs can change, and commencement dates may differ for Corporation Tax and Income Tax. |
| Use professional judgement | Many asset and vehicle questions depend on facts, evidence and judgement that a public calculator cannot assess. |
| Keep evidence | HMRC, auditors, lenders and insurers may require supporting documents rather than calculator screenshots. |
You may use the Services for personal study, business planning, classroom learning, internal budgeting, general comparison, rough estimates and professional illustration. You may share links to our pages and may print, save or screenshot calculator outputs for your own records, provided you do not remove branding or misrepresent the output as professional advice from us.
Qualified accountants, bookkeepers, tax advisers and finance professionals may use the calculators as part of their internal workflow or client discussions, provided they apply their own professional judgement and independently verify any result before giving advice, submitting returns or issuing reports. You may not present our result as a final professional computation unless you have checked and adopted it as your own work.
Teachers, bloggers and website owners may link to our pages or quote short extracts with attribution. Any larger republication, copying of code, copying of calculator design or creation of a competing cloned tool requires written permission.
You must not use the Services in a way that harms the Site, misleads others or breaches the law. Prohibited use includes, but is not limited to, scraping content at scale, copying source code, reverse-engineering calculators, attempting to bypass security, overloading servers, injecting malicious scripts, framing pages in a misleading way, using outputs in spam, or implying that we have endorsed your business.
You must not use calculator results to file tax returns, obtain loans, mislead buyers, mislead sellers, manipulate insurance claims, avoid legal obligations or provide regulated advice without independent verification. You must not use the Site for unlawful activity or in breach of data protection, computer misuse, consumer protection, tax or intellectual property laws.
Automated access, bots and bulk extraction are not allowed without our prior written permission. We may block IP addresses, user agents or access patterns that appear abusive, automated, security-threatening or materially disruptive.
Our calculators are designed to process inputs in your browser. In normal use, the figures you type into a calculator are used to generate an on-screen result and are not intended to be stored as a user account or transmitted as a personal financial record. However, normal website hosting, caching, security logging and analytics may still involve technical data such as IP address, browser type, device information and page visits.
Do not enter sensitive personal data into calculator fields. The tools are intended for numerical and business planning inputs such as asset cost, mileage, useful life, depreciation rate or pool value. You should not enter National Insurance numbers, bank details, passwords, private addresses, medical information or any confidential client data.
Our Privacy Policy and Cookie Policy explain how we handle personal data, cookies and technical logs. If there is any conflict between this section and the Privacy Policy, the Privacy Policy controls how personal data is handled.
Unless otherwise stated, the Site design, text, calculator logic, code, tables, page layouts, examples, brand names, graphics and downloadable materials are owned by us or licensed to us. They are protected by copyright, database rights, trade mark law and other intellectual property rules.
You may view the Site and use calculators for their intended purpose. You may not copy, reproduce, sell, lease, sublicense, redistribute, mirror, scrape, white-label or adapt substantial parts of the Site without written permission. You may not create a competing calculator site by copying our structure, wording, source code, examples or design.
Where we link to official or third-party resources, those third parties retain their own rights in their content. References to HMRC, GOV.UK, RICS, HAGI, Hagerty, CAP HPI, Glass’s Guide or other organisations do not imply endorsement unless explicitly stated.
The Site may link to official guidance, valuation services, government pages, accounting bodies, tax resources, partner tools or other websites. Links are provided for convenience and education only. We do not control external websites and are not responsible for their content, availability, accuracy, privacy practices, security or terms.
If you click a third-party link, you leave our Site and should read that organisation’s own terms and privacy policy. External resources may change after we link to them, and a page that was accurate at the time of writing may later move, update or become unavailable.
We aim to keep the Services available, but we do not guarantee uninterrupted access. The Site may be unavailable due to maintenance, technical failures, hosting problems, updates, security issues, internet outages or circumstances outside our control.
We may update, suspend, remove, replace or redesign any calculator, guide, page, default rate, layout or feature at any time. We may also correct errors without notice. Historical outputs should not be assumed to remain valid after an update, because a calculator may later use different assumptions or rates.
Some calculators require JavaScript. If your browser blocks scripts, cookies or local functionality, a calculator may not work correctly. You are responsible for using a secure, up-to-date browser and checking that results display as expected.
To the fullest extent allowed by law, we exclude liability for loss arising from use of the Services, reliance on calculator outputs, outdated rates, data entry errors, technical failures, loss of profit, loss of business, loss of opportunity, loss of goodwill, tax penalties, HMRC enquiries, valuation disputes or decisions made using our content.
Nothing in these Terms excludes or limits liability where it would be unlawful to do so. This includes liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation or any other liability that cannot be excluded under applicable law.
If a court finds that we are liable despite these Terms, our total liability to you will be limited to the greater of £100 or the amount you paid us for the specific Service giving rise to the claim. Since the Services are currently free, this limit is intended to reflect the educational nature of the Site. This limitation does not affect mandatory rights that cannot legally be limited.
If you are using the Site as a consumer, nothing in these Terms is intended to reduce your statutory rights. UK consumer law may prevent businesses from excluding certain responsibilities or using unfair terms. These Terms should be interpreted in a way that is fair, transparent and consistent with mandatory consumer protection rules.
The Site is primarily a free information service. We do not currently charge consumers for calculator access. If paid products are added later, those products may have additional terms covering payment, cancellation, refunds and support.
We may update these Terms to reflect changes in our Services, law, technology, calculator features, business structure or risk controls. When we make material changes, we may update the “Last updated” date, add a notice on the Site or otherwise make the revised Terms available.
Your continued use of the Site after updated Terms are published means you accept the revised Terms. If you do not agree with a change, you should stop using the Services. The current version will normally be available at /terms-of-service/.
These Terms are governed by the laws of England and Wales, unless mandatory consumer protection rules in another UK jurisdiction apply. If a dispute cannot be resolved informally, the courts of England and Wales will have jurisdiction, subject to any consumer rights that allow you to bring proceedings elsewhere.
Before starting formal proceedings, we encourage users to contact us with details of the issue so we can try to resolve it quickly and fairly.
Questions about these Terms can be sent through our website contact page or by email if an email address is displayed on the Site. Please include the relevant page URL, calculator name, date of use and a clear explanation of the issue.
